Abstract
Embodiments of a quill stop are disclosed. The quill stop can move between an open and closed position. The quill stop has a left and a right securing member, a locking element, a right arm, a left arm, and a left arm spring. The right arm can actuate the locking element out of engagement with a locking projection so that the right securing member and the left securing member can move relative to each other and allow a rod to be inserted between them. The locking element prevents unwanted actuation of the quill stop during operation.
Claims12
An apparatus comprising:
- a quill stop, capable of moving between an open position and a closed position, comprising:
- a left securing member comprising a locking element pivot;
- a right securing member comprises a locking projection;
- a locking element that defines a locking projection receiving space and comprises a locking element abutment, wherein the locking element is configured to rotate about the locking element pivot;
- a right arm comprising a right arm actuator;
- a left arm defining a left arm spring space;
- a left arm spring located at least partially inside the left arm spring space, wherein the left arm spring biases the locking element away from the left arm and the locking element into abutment of the locking projection;
- a securing spring coupled to the left securing member and the right securing member, wherein the securing spring biases the left securing member and the right securing member together;
- a right arm abutment;
- and
- a left stop
- wherein:
- when the quill stop is in the closed position, the right arm actuator abuts the locking element abutment, and the locking projection is located inside the locking projection receiving space;
- when the quill stop is in the open position, the locking element abutment abuts the locking projection, the left arm spring is compressed, and the securing spring is expanded;
- and
- when the quill stop is in the closed position, and a sufficient compression force is applied to the left arm and the right arm to cause movement:
- the right arm will rotate in relation to the right securing member;
- the right arm actuator will move the locking element so that the locking projection is freed from the locking projection receiving space;
- the locking element will cause compression of the left arm spring;
- the right arm will abut the right arm abutment;
- the right securing member will rotate in relation to the left securing member as the right arm abutment uses the left stop as a fulcrum;
- and
- the locking element abutment will abut and slide along the locking projection as the left securing member and the right securing member separate.

- a right arm abutment;
- and
- a left stop
- wherein:
- when the quill stop is in the closed position, the right arm actuator abuts the locking element abutment, and the locking projection is located inside the locking projection receiving space;
- when the quill stop is in the open position, the locking element abutment abuts the locking projection, the left arm spring is compressed, and the securing spring is expanded;
- and
- when the quill stop is in the open position, and a sufficient compression force preventing movement is removed from the left arm and the right arm:
- the securing spring biases the left securing member and the right securing member together,
- the locking element abutment will slide along the locking projection and engage the right arm abutment;
- and
- the locking element will cause the right arm to rotate about the right arm securing member.
